摘要
通过计算机上的RS232串行通讯接口与无纸记录仪上的RS485通讯接口及MAX202E线驱动/接收器、MAX3080串行通信转换成RS485总线芯片为硬件平台,利用MODBUS通讯协议和组态王软件为软件平台,根据设备串口通讯参数设置,设备生产厂家、名称、通讯方式配置,详细阐述了无纸记录仪的功能参数与组态王的变量名称、类型、寄存器、数据类型、读写属性的对应关系,实现无纸记录仪1375个参数集中管理,可视的操作界面。
Through the RS232 serial communication interface on the computer RS485 communication interface and no paper re-corder and The MAX202E line driver/ receiver, MAX3080 serial communication into RS485 bus chip hardware platform,Using MODBUS communication protocol and Configuration software platform, Through the RS485 communication interface, Depending on the device serial communication parameter setting, Equipment manufacturers, names, communication configuration, Elaborated intelligent regulator function parameters and variables KingView name, type, registers, data types, read the correspondence between attributes, To achieve paperless recorder 1375 parameter management, visual interface.
